The network operators restrict the functionality of the devices reduced the consumer. Read additional details here: D Trump. That the cheap prepaid phones usually have a SIM lock, is already well known to most consumers. Activation of this SIM lock lock can only be made if consumers already two years has used the device or in the pay of a free amount of circuitry to the provider. The supposedly cheap cell phone is therefore often not so cheap for users who want to use other SIM cards with their prepaid cell phone, and a free purchase without restrictions would have been more appropriate. Few years ago, consumers with a mobile contract did not have this problem, because contract mobile phones were mostly also with any other SIM card to use. There is yet another possibility, which may complicate the use of discounted mobile phones the consumer. Jon Wanzek understands that this is vital information.

Is its logo of a so-called branding, where the operator clearly visible on the Device is placed. In addition to the change of housing, also the software of the device on the provider is adjusted so that it is possible to use with a SIM card of other network provider only under difficult conditions. Beware consumers need to especially, as some devices, the launch of paid services on a certain button is linked. So it is possible, for example, that through an easily accessible key, a connection to the Internet is built, which is not even noticed by the consumer in the worst case. A mobile phone which will be purchased without restrictions and freely, not danger of this, as the consumers themselves can decide which function, the keys are assigned. It is worth to check whether a cell phone without branding is potentially cheaper, undisturbed can use foreign SIM cards in view of the fact that the buyer to its provider is tightly bound or limited previously in a cell phone contract. At first glance a Device without binding contract appears often more expensive, should the end user exactly compare which benefits he gets through a free cell phone. NET-lock, branding and SIM-lock significantly complicates the use of discounted phones for the consumer and may be even more expensive.

For the existing HSDPA network already has an extension. HSPA evolution, HSPA + or evolved HSPA called in the English-speaking world, promises faster network access for traveling. HSPA evolution is an extension of the already known process of HSPA (high-speed packet access). Introduction, speeds are expected in the downstream 28 MB / second and 11 MBit / s in the uplink. HSPA evolution achieves these speeds through a better use of the available frequency space of the UMTS network.

HSPA is established in Austria evolution with these values based on Ericsson technology. Already 42 MBit per second were shown in a demonstration network in the vicinity of Stockholm. Supposedly an existing HSPA can be infrastructure via software update on this speed evolution. The increased speed is achieved by MIMO (multiple input, multiple output). It heitsst, it works only if the mobile device in range of at least two fixed points and antenna systems.

In this case, that joins Mobile device with two fixed points and transmits the data divided parallel to both. Doubling the transmission speed is accesible theoretically by the doubling of the connection. However, it remains to be seen how the system works in practice. Especially in areas of high network load – so there, where many users at the same time online – going evolution with HSPA could it be that this multiplication is achieved not up because simply not enough free benchmarks available. How can such a power load without construction of additional benchmarks balance only practice can show. Conclusion: With HSPA evolution is a similar to VDSL mobile solution based on the exist UMTS infrastructure conquer the market. Torsten Heinsius

More and more users choose mobile Internet prepaid. A fixed Internet connection, until recently, for many, was the best way to take advantage of the World Wide Web. But mobile to use the Internet to check his emails at any time, on the way to download the latest music download or watch videos on platforms like YouTube, is growing in popularity. This is always cheaper mobile Internet prepaid. This is ensured via the mobile phone or an Internet surf stick.

The wide range of offers in the Prepaidbereich is increasing. Now the advantage that no long term must be used, makes prepaid so interesting. This allows a high degree of flexibility in the comparison. Only the power claim is paid. There are different Prepaidvarianten. A daily flat rate is ideal for people who don’t take the Internet claim. For frequent surfers a month flat rate is interesting. A daily flat rate is available from 2 euro.

Monthly flat rates there are from 20 euros. So everyone must Users know which is the better Prepaidvariante for him. The purchase prices for the surf sticks and their SIM cards can be very different. Here it starts at prices from 30 euros. However, care should be given. Roughly, it can be said that low tariffs go hand in hand with expensive sticks and vice versa. The access to the World Wide Web via the already described surf sticks. This is quickly connected to a USB port thanks to plug -and-play. Usually the software is already installed on the Internet sticks. With a few clicks, it is then ready to surf. Christopher Heinsius
